IPC: H01L21/52
Filed: 1992-09-22
Abstract: PURPOSE:To reduce the number of processes by soldering a semiconductor device and a heat sink and soldering the heat sink and a circuit board in one and the same process without doing those solderings separately when mounting the semiconductor device on the circuit board through the heat sink. CONSTITUTION:An oxidized region 6 is formed around a semicoductor device mounting area 7 on a heat sink 1.
